MACHINE FOR MANUFACTURING CANS..

SPECIFICATION forming part of Letters Patent N0. 753,966, dated March 8,1904.

Application filed March 27, 1902.

.To all whom it may concern:

Be it known that I, DANIEL L. EUsTIcE, a citizen of the United States,residing at Galena, county of Jo Daviess, and State of Illinois, haveinvented certain new and useful Improvements in Machines forAyManufacturing Y Gans; and I do hereby declare the following to be afull, clear, and exact description of the invention, which will enableothers skilled in the art to which it appertains to make and use thesame.

My invention relates to machines for the construction of cans, and moreespecially to machines for securing the bottoms to the cans and forrolling the tops of the cans; and one of the objects is to hold the canin a given and determined position whereby an inexperienced andunskilled operator can bottom the cans readily and at the same time maketight joints and uniform cans.

Anotherl object is to save the expense of extra handling of the can inits various details in construction.

The manner in which these objects and others of less moment areaccomplished is set out in detail in the following specification whentaken in connection with the drawings accompanying the same.

Figure l is perspective view of the machine complete'. Fig. 2 is an endelevation of the lever and its grooved rollers, which are used foruniting the bottom to the sides of a can. Fig. 3 is a plan View of thelever shown in Fig. 2. Fig. 4 is a plan View of the U-shaped frame,showing the journal-boxes for the rotating shafts and showing the upperarm of the standard in section. Fig. 5 is a detail, partly in sectionand partly in elevation, of the adjustable connection for thecan-supporting frame. Fig. 6 is atransverse section on the line 0c w ofFig. 5. Fig. 7 is a plan view of one of the can-supporting plates ordisks. Fig. 8 is a vertical section of Fig. 6. Fig. 9 is a bottom viewin elevation of the plate and rollers for rolling the can and beadingthe top edge of the can; and Fig. 10 is a vertical section of the plateillustrated in Fig'. 9, showing the position of the can when operatedupon.

sponding parts appearing in the several illustrations.

Referring to the drawings, l represents the upright frame, and 2 itsbase, formed integral therewith. There is also cast with the framesthree arms 4, 5, and 6. To the arm4 are pivoted two pulleys 8 and l0,mounted upon a common shaft Il, and to the front edges of the arms 5 and6 is secured a U-shaped frame 12.

The frame 12 is of U shape, and there is cast integral with its upperarm half of two boxes or bearings 14 and l5, in which the two shafts 16and 20, presently to be described, rotate. With the lower arm are casthalf of the two boxes 17 and 18, in which the same shafts 16 and 20 alsorotate. The oth er halves of the boxes 14 and 17 are bolted to the rearsides of the arms by bolts 19, forming complete boxes for the shaft 16,while the other half of the boxes l5 and 18 are formed on the ends ofthe arms 5 and 6 and have matching relation therewith to form bearingswith the shaft 20.

On the top of the shaft 20 is rigidly secured a driving-pulley 22, andupon the same shaft 20, between the arms of the frame 12, is fastenedanother pulley 24. Upon the shaft 16, between the arms of the frame l2and in the same horizontal plane as the pulley 24, is a pulley 25. Thesetwo pulleys are connected together by an endless belt 27. By this modeof construction whenever the shaft 2O is rotated the shaft 16 will alsobe rotated.

Upon the lower end of the shaft 16 is secured a plate 30. (Shown inFigs. 9 and l0.) In the under side of this are pivoted beadformingrollers 32, which are beveled and provided with grooves 33. By means ofthis construction whenever the plate 30 is rotated by the shaft 16, withthe upper edge of the can in the grooves 33, the edge of the can will berolled over on the inside of the can, forming a rim on the top of thecan. In Fig. lO the can is shown with a bead formed on one side, as atA, while on the other side the edge of the can is shown engaged by theouter edge of the groove in the roller, as at B, which is its positionprior to the formation of the bead. To the lower end of the shaft 20 isattached a plate 35, which has a flat under sur- IOO face against whichthe bottom of the can is brought to bear.

Extending from the upright l beneath the arm 6 is a grooved guideway36a, having slots 36h, through which bolts 36c extend. An arm 36 ispierced and held to the guideway by these bolts 36", and by thisconstruction the arm 36 may be adjusted transversely with respect to theupright, so that the arm may be moved toward or from the plate 35. Theouter end of the arm 36 terminates in a cylinder or box 37, in which isfastened the shaft 40 by the screw 41. On the upper end of the shaft 40is pivoted a lever 44, carrying two grooved wheels and 46 for bendingand securing the bottom of the can to the sides thereof. In theperiphery of the wheel 46 is a groove 42 and in the wheel 45 adifferentshaped groove 43, (both shown in Figs. 2 and 3,) the object ofwhich will presently appear.

Against the front side of the frame 1 below the arm 36 is adjustablyfastened a plate 48 by the bolts and nuts 49, the heads of the boltsfitting in the longitudinal groove 49 of a plate 49h, whereby the plate48 may be adjusted vertically by u'nscrewing the nuts and releasing theheads of the bolts from binding engagement with the walls of the slot,as will be clear by reference to Figs. 5 and 6 of the drawings. Integralwith the plate is a cylindrieal arm 50, which projects out at rightangles to the plate 48 and terminates in a lateral extension 51, inwhich are formed semicircular longitudinally-disposed bearing portions.

Bolted to this lateral extension is a plate 53, which has similarbearing portions arranged in matching relation with the first namedbearing portions and which form journalboxes 52 and 54. l

Mounted in the journal-boxes 52 and 54 are rotary longitudinally-movableshafts 55 and 59, each of which has can-supporting plates 56 and 60attached to their upper ends. In the plate 56 are a plurality of annulargrooves 58, in which the end of the can is inserted when the can is tobe bottomed. These grooves are of such depth and width as to permit thesides of the can to extend a short distance therein and be snuglyembraced at the sides around the edges, so that the cans are accuratelycentered and are prevented from becoming displaced during the bottomingthereof, while at the same time the edges are prevented from beingdistorted by pressure. The plate 60 is formed with an annular depressedportion, as at 58, so that when the can has been bottomed it may beplaced on the supporting-plate 60, with its bottomed end in thedepressed portion, and the annular iange formed by such depressioninsures a proper centering of the can. It will be understood that if itbe desired to roll the top edge of the can before bottoming it a platewith grooves similar to the plate 56 may be substituted for the plate60, so that the side edges of the can may rest in grooves while theopposite edge thereof is being beaded by the rollers 32.

The plate 48 can be adjusted vertically for the purpose of adapting themachine to operate upon cans of different heights. This is accomplishedby raising or lowering the plates `56 and 60, and thus varying' thespace between these plates and the plates 30 and 35.

The plate 48 is bifurcated at its lower end, and between the arms ispivoted a lever 6l, one arm of which extends forward of the frame and towhich is bolted a rest 62, upon which set the shafts 55 and 59 insockets 63 and 64. Between the arm 50 and the forward arm of the lever6l is placed a spring 65, which normally holds the lever and restdepressed. Another arm 68 of the lever 6l extends in the rear,and to itis adjustabl y pivoted a connecting-bar 70. This connecting -bar runsdown and is pivoted to a foot-lever 72, which lever is pivoted to afulcrum 73, attached to the base 2. There is also cast integral with therear of the frame a bracket 75, extending down parallel with the frameand forming at its lower end a bearing for the driving-shaft 78. Thisshaft 78 also has another bearing in the rear of the frame. On the shaft78 are mounted two active pulleys 8l and 82 and an idle pulley 84. Thepulley 81 is connected with and operates the pulley 22 by an endlessbelt 85, which passes over the pulleys 8 and 10. The pulley 82 may beconnected to the driving' power by a belt 88.

The manner of operating my device is substantially as follows: The poweris applied to the pulley 82 by the belt 88. This will rotate the pulley81 and the pulley 22. As the pul- IOO ley 24 is upon the same shaft asthe pulley 22,

it will also rotate this pulley and pulley 25 and the plates 30 and 35.When these pulleys are rotated, the operator takes the body of aninverted can with the bottom loosely upon the body and places it in oneof the grooves 58 on the top of the plate 56. He then places his footupon the lever 72 and draws down the arm 68, which forces up the rest 62and with it the can upon the plate 56 against the revolving plate 35. Itwill be seen that the can is then rigidly held between the plates 35 and56 and will rotate with the plate 35. He then draws the lever 44 towardhim, which brings a groove 42 in the wheel 46 in contact with the edgeof the bottom and bends it over. Then he reverses the lever 44 andbrings the groove 43 in the wheel 45 on the other arm of the lever incontact with the rim on the bottom of the can, and this finishes thebottoming of the can. The operator then releases his foot from the lever72, and the spring 65 forces the rest 62 downward, and with it thc plate56. The operator then places the can right side up on the plate 60. Theupper edge of the can resting upon the plate 60 will come in contactwiththe wheels 32 in the plate 30 and rolll the edge of the can inward,and

IIO

thus form a rolled top to the can, as shown in Fig. 10.

It will be seen that it will not require skilled workmen to operate thismachine, as the grooves 58 in the plates 56 and 60 always will determinewhere the cans should be placed. 'Ihe can will also always remain inthat position with reference to the plate above it, and all that isnecessary for the operator is to place the cans in the groove and drawthe lever 44 toward him or reverse it, and in rolling the edge of thecan there is nothing for him to do except steady the can in itsposition. Besides, the can is brought up by the lever and only onehandling of the cans is necessary. Where great rapidity is desired, twooperators may be used to good advantage, the one operating the can inbottoming it and the other taking the can and rolling it and placing itin the package.
